Impreza WRX GD Rear Noise Causes And Countermeasures

About a month has passed since the car was delivered as a used car. From the beginning, I was worried about the abnormal noise from the rear while driving, such as when starting, stopping, or overcoming steps. Possible causes are … 1. I don’t know about Subaru, but the deterioration of the stabilizer link, which is common in Honda cars, etc2. Loose bolts including the upper mount3. The trunk striker is hitting somewhere4. Loads including genuine jacks I tried and errored considering the above causes, but no improvement was made. When the coil spring expands and contracts, a force in the direction of rotation is generated, and I thought that the deviation would generate noise, but it seems to be wrong. When I unload the luggage in the trunk and put your weight on it like straddling a spare tire and shake the car body up and down, the noise is generated. It is a photograph of the rear shock absorber. I tried cleaning the damper part, thinking that the damper was not moving well and there was a sound that would get caught in the seal when it was activated.

I think the cause of cavitation is that it has sucked in air, but I don’t know where it came from, and apparently there is no oil leakage. In any case, Subaru’s hydraulic pumps of this age seem to have troubles over the years, including the Legacy, so I’m thinking of replacing them with rebuilt pumps to see the improvement in symptoms. First of all, I got a rebuilt pump, but my GDA power steering pump is a model called 34430FE041, which seems to be out of stock in the rebuilt market. I had a little trouble buying it online (34430FE041 seems to be common with 040, 070 and 071). At the same time, I ordered two hoses connected to the power steering tank that could be easily replaced and a metal gasket on the high pressure side that connects to the pump and prepared them.
